In the simplest form, the present invention discloses the utility of combining dry reagent electrochemical enzyme based biosensors with apoenzyme reactivation technology to produce a novel diagnostic test platform technology capable of detecting a wide range of analytes, and capable of operating in a dry or wet, in vivo or in vitro, environment.
Meaning of “apoenzyme” in the English dictionary
From here, the electrons may in turn pass into electrical conduits or traces 55where an outside electrical measuring apparatus can then detect the reaction. In use, a patient test sample 10 such as blood or plasma is applied to the test device.
Pregnancy and ovulation markers include early pregnancy factor, human chorionic gonadotropin and luteinising hormone LH. The immunochemical detector device of claim 12in which the test antigen is selected from the group consisting of markers for sepsis, angiogenesis, pregnancy, ovulation, cardiovascular status, infectious disease, drugs of abuse, therapeutic drugs, kidney disease, ischemia, coagulation and reacfivation diagnostics.
The invention discloses a method in which dry reagent enzyme based electrochemical biosensors, which are in a relatively mature form due to the extensive amount of development pioneered by the blood glucose monitoring industry, may be simply adapted to perform tests for blood coagulation, enzymatic activity, or immunochemical assays for antigens present in a fluid sample. Fad-labeled specific binding assay monitored with apoglutathione reductase or apolipoamide dehydrogenase.
Such recombinant antibody-apoenzyme fusion proteins could be useful in a number of different types of electrochemical immunoassays. After coupling, reaction quenching, and washing according to the Polysciences protocol, the apoglucose coupled latex microbeads are spun down in a microfuge, and resuspended in a 1.
However test enzyme 19 does not create the prosthetic group. If supplemental electrical power is needed to drive the device, the device’s onboard electronics can be designed to draw power from an internal battery, from radiofrequency signals, magnetic coupling induction signals, or other means.
In the body, the extrinsic coagulation pathway is triggered when thromboplastin, a natural membrane-tissue factor component of the blood vessel’s endothelial lining, is released from the interior of the cells due to cellular damage. Reacitvation apoenzyme stimulation test is a popular method for measuring vitamin B6.
Federation of European Biochemical Societies. A plastic cover should be laminated on top of the porous carbon electrode—support layer with a mil thick plastic spacer, creating a lower support, porous carbon electrode, upper plastic support structure as shown in FIG.
Such allosteric enzyme regulation may be done by binding of an allosteric moiety, by covalent enzyme modification e. The device of claim 1in which said electrochemical apoenzyme is glucose oxidase, and the complex contains FAD as the prosthetic group or activation moiety.
Educalingo cookies are used to personalize ads and get web traffic statistics. Apoglucose oxidase conjugated microbeads: Typically amplification enzyme substrate 14as well as other reaction chemicals coagulation initiators, buffers, viscosity modifying polymers, and apoenzyme stabilizing agents such as trehalose are also present.
Apoenzymes 131 additionally contain amplification substrate-binding sites 3 and the area immediately behind In some situations, it may be advantageous to include multiple electrodes in a single test strip in order to obtain both positive high and negative low onboard controls for the reaction.
